Biological Assessment
18 species of FRESHWATER FISH (50% endemic to the
corridor)
26 species of AMPHIBIANS (25% endemic to the country,
majority are confined to the corridor)
69 species of REPTILES (29% are endemic to the country)
279 species of BIRDS (10% are endemic to the country); 34%
of bird species are migratory, making the region a vital flyway
for migratory birds
58 species of TERRESTRIAL MAMMALS, 19 or 33% are
endemic to the country, 16 are restricted to the corridor

16. Priority Site:
Mt. Mantalingahan
Protected Landscape
. . . a new protected area
(2004 to present)
. . . 126,000 hectares

17. Site Outcome:
Mt. Mantalingahan Protected Landscape
One of the 10 sites of the Alliance for Zero
Extinction (AZE) in the Philippines;
One of the 11 important bird areas in
Palawan;
One of the 17 terrestrial key biodiversity
areas (KBA) in Palawan;
The largely forested mountain range
covers several critical watersheds that
are extremely valuable to lowland
agricultural economy.
The large expanse of forest also plays a
macro-climatic function by acting as a
significant carbon sink.

18. Site Outcome:
Mt. Mantalingahan Protected Landscape
Location: South of Palawan Province, Philippines
5 Municipalities covered: Bataraza, Brooks Point,
Quezon, Rizal, Sofronio Espanola
Population: at least 3,000 HH
of indigenous Palaw’an
Key Species: Palawan soft-furred mountain rat (Palawanomys
furvus), Philippine cockatoo (Cacatua haematuropygia), Palawan
striped-babbler (Stachyris hypogrammica)

19. Site Outcome:
Mt. Mantalingahan Protected Landscape
Legal Requirements
1 Compilation of maps & technical
descriptions
2 Initial screening
3 Public notifications
4 Initial consultation
5 Census & registration of PA

LAND-USE ANALYSIS
Method
Assess optimality of existing and
planned land-uses Suitability assessment of existing
and proposed land-uses
Estimate minimum requirements to
conserve water, soil and biodiversity o Suitability – compatibility to site
quality (i.e., slope)
Recommend strategies to achieve
o Suitability – onsite and offsite
right mix of development and
impacts (streamflows and soil
conservation uses
erosion)
Facilitate update of municipal land o Suitability – consistency with
use plans legal framework (i.e., legal
classification of the land)
Provide inputs to the protected area
management plan o Suitability – in terms of
financial viability
